Hit the Mediterranean coast and paddle out over ruins submerged in crystal-clear water. Pillars, stairs, and harbor walls are right beneath you, and best of all, you'll be a world away from the touristy towns of Marmaris, Bodrum, and Kusadasi. About 20 miles east of Kas is the tiny village of Ucagiz, set along a stretch of coastline liberally studded with the ruins of ancient Lycian settlements. Rent a two-person kayak, paddle out, and look down over the submerged ruins of ancient Kekova. Come for the day and stop for a swim in the azure water. Then tuck into a fish lunch in the sleepy village of Kale. It's a longish haul so it pays to have powerful shoulder muscles. In all, it'll cost you about $50.
